Write and equation that represents the reaction of 2% ethanolic PBP solution with 4-methylcyclohexene and name the product
Calculate concentrations of OH- and the pH of each basic solution. Since NaOH donates on OH- ion for each NaOH molecule, the OH- concentration is equivalent to the NaOH molarity. The pOH is calculated as -log[OH-] and the pH is calculated as 14-pO..
what spontaneous reaction will occur in aqueous solution among the ions Sn4+, Sn2+, Co3+, and Co2+ ? What will be the E°cell for this reaction?
What is the percent by mass of NaHCO3 in a solution containing 70 g of NaHCO3 dissolved in 700 mL of H2O?
The neutralization of 50.0 mL of 1.00 M hydrochloric acid with 50.0 mL of 1.00 M sodium hydroxide causes a 6.7°C increase in temperature. Predict how the following changes to the experimental protocol would affect the value of the change in temper..
what can you conclude about the process of breaking bonds in the liquid as compared to the gas phase? Explain the difference in the heat of formation values between the two phases.
A solution of methanol, CH3OH, cotains 55.0 grams of methanol in 100. mL of water solution. What is the molarity of methanol in the solution?
a 14.0 g sample of iron was heated from 10.0C to 20.0C it absorbed 15.2 of energy as heat based on this data what is the specific heat of this piece of iron?
A student found that a brand B tablet would neutralize 0.011 moles of HCl per tablet. Which is the better buy, brand A or brand B? Why?
what mass of solid sodium formate (of mw 68.01) must be added to 105 ml of 0.55 mol/l formic acid(HCOOH) to make a buffer solution having a ph of 3.96? ka=0.00018 for HCOOH
Carbonyl fluoride, COF2 is an important intermediate used in the production of fluorine-containing compounds. For instance, it is used to make the refrigerant carbon tetrafluoride
The standard enthalpy of formation of carbon monoxide is more esothermic than the sum of the standard enthalpies of formation of methane and water.
If 150 g of carbon reacts with 250 g Cl2 with an 85% yield, what is the mass of CCl4 produced
